Bug 245929

Description of problem:
When modifying a printer's default job options using system-config-printer,
occasionally the program will crash.  It doesn't seem to be repeatable by a
particular sequence of events, but does happen often when several options are
repeatedly added and removed.

NB: this is different from bug #230118, and occurs with fixed CUPS packages.

Version-Release number of selected component (if applicable):
system-config-printer-0.7.32.5-1.el5
cups-1.2.4-11.9.el5

How reproducible:
Often.

Steps to Reproduce:
1.Add three job options and click apply.
2.Remove the options and click apply.
3.Play around with adding and removing options, occasionally applying.
  
Actual results:
After several minutes the application crashes.

Expected results:
No crash.
